hi,

I have installed RHEL4 on my desktop machine . Done all the setting in /etc/pam.d and finally my rsh and rlogin works from my machine(rsh the same machine)

[root@linux tmp]# rsh 10.121.113.92

You have new mail.
[root@linux ~]#


10.121.113.92 is the ip address of my linux(same) machine
but when I tried rcp ( in the same machine)

[root@linux tmp]# rcp /tmp/work 10.121.113.92:/home/
10.121.113.92: Connection refused
[root@linux tmp]#

my /root/.rhosts file ( with 644 permissions)
[root@linux tmp]# more /root/.rhosts
10.121.113.92 root


Can someone please help me with this.
Actually there is a script that use rcp and I need to use that as it is

You really should move away from using r commands - the security for them is almost non-existent - almost anyone can pretend to be the host you're allowing in your .rhosts file. If you have a script rather than a binary that relies on these commands it would be very easy to convert from rsh/rlogin to ssh and from rcp to scp.

Of course you'll have to setup trusts to use ssh/scp but that isn't really difficult.

If you really want to use rcp have a look at the man page by typing "man rcp" - it tells you about authorization files needed.

Here's a good article http://www.informit.com/articles/art...p=169465&rll=1

thanks for the reply..

I have asked the developer to use SSH and SCP as of now.

Just want to know whether rcp needs ftp . in RHEL4 ftp does not come by default. I downladed the rpm , installed it and started the vsftd serverice.

I believe that rcp runs on port 514. Please let me know how to check whether my machine is listening on port 514 when i run rcp command.

I have disabled the iptables in my machine.

Try

netstat -tanp|more

as root

No - rcp and ftp use different protocols as does scp. You can have all 3 or any 2 or any 1 or none. rcp and ftp are very insecure so most Linux distros don't enable them by default but there is nothing preventing one from doing it. At least there has been some attempt to make ftp more secure with vsftp and rcp/rsh more secure with Kerberized versions but the best security is still obtained with ssh/scp.
